Examining the Evolution of Plant Growth Rate in Relation to Environmental Characteristics.

Growth rate is a significant plant trait involved in processes like competition and stress resistance. In a previous study, the growth rates of temperate tree species across ten genera were analyzed using two sources of data (dendrochronology and diameter-at-breast-height) to generate a dataset of growth rate. Using this dataset, we investigated the evolution of growth rate in relation to plant leaf ecophysiological and defense traits as well as native habitat climate and soil conditions. To accomplish this, as phylogenetic comparative approach was used. Phylogenetic generalized least-squares regression was used to assess correlations between growth rate and plant traits, as well as growth rate and habitat environment. This research strengthens our understanding of the drivers of plant growth rate evolution, while also applying this research to give insight to areas like forestry and forest management under climate change.
